The reference to private/auth is referring to dovecot's
authentication socket under postfix's chroot directory.
It's in /var/spool/postfix/private/auth, not /etc/postfix.
You have set that up in dovecot's config:
service auth {
unix_listener /var/spool/postfix/private/auth {
group = postfix
mode = 0666
user = postfix
}
unix_listener auth-userdb {
mode = 0600
user = vmail
}
user = dovecot
}
My version of that looks like:
service auth {
unix_listener /var/spool/postfix/private/auth {
mode = 0666
}
}
So it looks like that should be OK.
Does /var/spool/postfix/private/auth exist?
Mine has root as owner/group. Yours should
have postfix as owner/group. But that shouldn't
matter as long as the mode is 0666.
If not, check dovecot's log messages for problems with it.
But I don't know what to look for. The dovecot mailing list
folks might be more useful for that.
It should exist and be used by dovecot. If you have lsof installed,
you can check that:
> sudo lsof /var/spool/postfix/private/auth
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
dovecot 17341 root 53u unix 0xffff8e43c69f7400 0t0 16873340
/var/spool/postfix/private/auth type=STREAM
auth 1521507 dovecot 13u unix 0xffff8e43c69f7400 0t0 16873340
/var/spool/postfix/private/auth type=STREAM
auth 1521507 dovecot 21u unix 0xffff8e43c417c800 0t0 69451443
/var/spool/postfix/private/auth type=STREAM
auth 1521507 dovecot 22u unix 0xffff8e43c9fc2400 0t0 69453124
/var/spool/postfix/private/auth type=STREAM
Something else that might or might not be a (different)
problem is that the TLS certificate at
mail.sizzlelicks.com doesn't certify the domain
mail.sizzlelicks.com. Its list of domains contains
sizzelicks.com and www.sizzelicks.com but not
mail.sizzelicks.com. That might cause problems with
Thunderbird trying to connect for IMAPS. I think you
reported such an error message earlier. So you might
want to add the mail.sizzelicks.com domain to that
certificate. But that's not related to the failure to
connect to the dovecot auth socket.
